Description
Verfahren zur Darstellung von 5' : 5"-Dibenzoyl-amino-1:1' :<B>5:</B> 1"-tr ianthr imidcarbazol. Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Darstellung von 5':5"- Dibenzoylamino-I :1':<B>5:</B> 1"-trianthrimidcarba- zol, welches sich dadurch kennzeichnet, dass man 5':5"-Dibenzoylamino-1:1':5:1"-trian- thrimid zuerst mit wasserfreiem Aluminium chlorid und dann mit einem Oxydationsmittel behandelt.
Die neue Verbindung hat folgende Formel:
EMI0001.0010
Sie ist ein Küpenfarbstoff, welcher Baum wolle in hellen, orangen Tönen färbt.
Die Behandlung mit wasserfreiem Alu ininiumehlorid wird zweckmässig in Gegen wart eines Verdünnungsmittels, z. B. Nitro- benzol oder Pyridin, durchgeführt. Als ge eignetes Oxydationsmittel seien beispielsweise ein Bichromat in verdünnter Schwefelsäure oder eine wässerige alkalische Hypochlorit- lösung erwähnt.
<I>Beispiel:</I> 10 Teile 5':5"-Dibenzoylamino-1:1':5:1"- trianthrimid, das durch Umsetzen von 1 Mol. 1:5-Diamirioanthracliinori mit 2 lMol. 1-Chlor- 5-benzoylanthr.lchinori oder durch Umset zen von 1 112o1. 1 : 5 -Dichloranthraehinon mit 2 üfol. 1-Amino-5-benzoylantlir-achinon erhalten werden kann, werden in 100 Teilen Nitrobenzol suspendiert;
dann werden 50 Teile fein gemahlenes, wasserfreies Aluminium chlorid allmählich, bei Raumtemperatur be ginnend, hinzugesetzt. Die Temperatur wird alsdann auf 60-650 C erhöht und während 10-15 Minuten auf dieser Höhe erhalten, worauf man sie auf Raumtemperatur ab fallen lässt. Das Gemisch wird in Eiswasser eingetragen und das Nitrobenzol durch Ab destillieren mittels Dampf entfernt. Das ent stehende Produkt wird abfiltriert, mit Wasser gewaschen und getrocknet. Es wird dann mit Kaliumbichromat in verdünnter Schwefel säure behandelt.
Die so erhaltene Verbindung, ein Küpen- farbstoff, färbt Baumwolle in hellen, orangen Tönen.
Process for the preparation of 5 ': 5 "-dibenzoyl-amino-1: 1': <B> 5: </B> 1" -tr ianthrimidcarbazole. The present invention relates to a method for the preparation of 5 ': 5 "- dibenzoylamino-1: 1': <B> 5: </B> 1" -trianthrimidcarbazole, which is characterized in that 5 ': 5 "-Dibenzoylamino-1: 1 ': 5: 1" -trian- thrimide treated first with anhydrous aluminum chloride and then with an oxidizing agent.
The new compound has the following formula:
EMI0001.0010
It is a vat dye that dyes cotton in light, orange tones.
The treatment with anhydrous aluminum ininiumehlorid is expedient in the presence of a diluent such. B. nitrobenzene or pyridine performed. A suitable oxidizing agent is, for example, a bichromate in dilute sulfuric acid or an aqueous alkaline hypochlorite solution.
<I> Example: </I> 10 parts of 5 ': 5 "-dibenzoylamino-1: 1': 5: 1" - trianthrimide, which is obtained by reacting 1 mol. 1: 5-Diamirioanthracliinori with 2 mol. 1-chloro-5-benzoylanthr.lchinori or by reacting 1 112o1. 1: 5 -Dichloranthraehinon with 2 üfol. 1-Amino-5-benzoylantlir-achinon can be obtained, are suspended in 100 parts of nitrobenzene;
then 50 parts of finely ground, anhydrous aluminum chloride are gradually added, starting at room temperature. The temperature is then increased to 60-650 ° C. and maintained at this level for 10-15 minutes, after which it is allowed to fall to room temperature. The mixture is poured into ice water and the nitrobenzene is removed by distilling off using steam. The resulting product is filtered off, washed with water and dried. It is then treated with potassium dichromate in dilute sulfuric acid.
The compound thus obtained, a vat dye, dyes cotton in light, orange tones.
